MACHINE FOR SHUCKING- AND SHELLING CORN.

Specification of Letters Patent No. 18,342, dated October 6, 185'?.

To all whom it may concern:

Be it known that I, SANFORD KINGSBERY, of Carrollton, in the count-y ofCarroll and State of Georgia, have invented a new and Improved Machinefor Shucking and Shelling Corn; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making a part of this specification.

In the said drawings, Figure l, is a top view, and Fig. 2, a sideelevation of my improved machine for shucking and shelling corn; andFigs. 3, t, 5, and 6, are representations of detached portions of saidmachine.

Similar letters indicate like parts in each drawing.

A suitable supporting frame for my improved machine for shucking andshelling corn, is clearly represented in the accompanying drawings; thismay be constructed of any suitable material, and in any manner that willgive it the proper degree of strength and stability.

lUpon a suitable driving shaft D, which must be placed in a horizontal,or nearly a horizontal position, I secure a strong wheel A, of forty-twoinches in diameter or thereabout. One or both sides of said wheel I armwith peculiarly arranged lateral teeth; viz; at the distance of someeight or ten inches from the center of the face of said wheel, commencesthe innermost of two, three, or four annular rows g, g, of teeth, whichgradually increase in length from the innermost to the outermost of saidrows; and outside of the said annular rows of teeth g, g, the face ofthe wheel is armed with alternating fan-shaped series of teeth f, f,which gradually increase in length as they pass outward to the peripheryof the wheel.

In practice, I find that a suitable length for the actuating teeth onthe face of the wheel A, is to give the inner row of teeth g, the lengthof half an inch, and the extreme outermost teeth f, the length of oneinch and a half, and to have the intermediate teeth gradually increasein length from the former to the latter of the said enumerated teeth. Ialso find that the machine works well in practice, when the respectiveseries of teeth f, f, ocupy about the same space as the blank surfacesbetween said series of teeth. I have also discovered that when theentire face of the wheel A, is armed with teeth, the said teeth verysoon fill up with shucks and the machine becomes inoperative until itsactuating teeth have been cleaned of the said clogging shucks.

At the side of the face of the wheel A, and as near to its shaft aspracticable, I secure to the frame of t-he machine, the verticaltapering concave B, whose shape is represented by Figs. l, 5, and G, ofthe accompanying drawings; the inner surface of said concave being ofsuch a shape that all parts thereof will be equidistant from theextremities of the respective series of teeth f, and g, which projectfrom the face of the wheel A. Two of the said concaves can be used inconjunction with the toothed face of the wheel A; viz; one placed oneach side of the shaft of the said wheel. Both sides of the wheel A, maybe armed, with teeth, and therefore, four of the vertical taperingconcaves may be used in combination with one doubly-armed actuatingwheel.

The lower extremity of the tapering concave B, should extend but a veryshort distance below the shaft of the wheel A. When the lower end of thesaid concave is allowed to extend much below the axis of the wheel A,the cobs, I find, are broken into small pieces by the double action ofthe actuating teeth.

The unshucked ears of corn must always be inserted butt-end foremostinto the concave B; and when so inserted, if a sufficiently high speedis at the time imparted to the wheel A, the shucks will be at oncesevered from the ear and pass out at the side of the upper portion ofsaid concave, while the ear will descend and will lose every kernel ofits corn before its cob emerges from the lower end of said concave; theshucking operation being accomplished by the outer series of teeth f, f,and the operation of shelling being principally accomplished by theannular rows of teeth g, g.

That I claim as my invention and desire to secure by Letters Patent, is-

The combination of the toothed face, or faces, of the wheel A, with thetapering concorn, signed and witnessed this eighth day of August 1857.

SANFORD KINGSBERY.
